Justin Bieber cemented his status as the world's greatest teenager last night.
Clearly being a platinum selling pop star with over 21 million Twitter followers isn't enough for the young Canadian.
The Boyfriend singer was the first person to congratulate Floyd Mayweather Jr as the pint sized boxer defeated Miguel Cotto, at the MGM Grand Garden Arena, in Las Vegas.
Justin was Floyd's guest of honour at the big fight, even though other notable stars included rappers 50 Cent and Lil Wayne.
The unlikely friendship between Bieber and Mayweather has become so close that the 18-year-old was given unrivalled access to the undefeated boxer.
The pop star joined Floyd in the dressing room before the fight and was given great seats after escorting the champ into the ring.
Earlier in the day, Justin tweeted his new best friend and said: 'cinco de mayo.... #MayweatherCotto yeah @FloydMayweather today is a BIG day.'
The bromance continued when the champion athlete sent a message back to the Never Say Never singer.
Floyd said: '@justinbieber keep up the great work and thanks for the support #TheMoneyTeam. Enjoy the fight.'
